Put an $1,500 deposit on a car for my grandson. Had the deposit agreement for a used BMW signed by the manager. The next morning a sales manager called to apologize as our sales person did not realize this particular car had been sold. SERIOUSLY !!! I thought the days of dealers pulling stuff like this was over. Have purchased over 100 cars in my lifetime and this was a first. AVOID !
